Description

Technical Field

[0001] This utility model relates to the field of decorative panel molding technology, and more specifically, to a PVC decorative panel molding device. Background Technology

[0002] In the production of PVC decorative panels, the cooling process after hot pressing is not ideal. Some devices only cool from one side of the panel, resulting in slow and uneven cooling. This makes the panel prone to deformation due to uneven stress during cooling, reducing the product yield. Furthermore, existing cooling systems often fail to consider the impact of air humidity on panel quality. When humid, cold air comes into contact with the hot panel, condensation easily forms, further damaging the surface quality. Utility Model Content

[0003] Based on the above-mentioned technical problems, this utility model proposes a PVC decorative panel molding device.

[0004] A PVC decorative panel molding device, comprising:

[0005] The main body of the molding die is equipped with a conveyor track, which carries the decorative panel and allows it to pass through subsequent components along a preset path. The design of the conveyor track ensures the stable transport of the decorative panel during the molding process, providing the basic conditions for subsequent hot pressing and cooling.

[0006] Compression molding assembly: Located on the conveyor track of the compression molding body, its main function is to enable the decorative panel and PVC film to be formed by hot pressing. The compression molding assembly ensures that the decorative panel and PVC film are tightly bonded by precisely controlling the temperature and pressure, forming a high-quality finished decorative panel.

[0007] Cooling component: Located behind the molding assembly, it is connected to the refrigeration equipment. The cooling component is designed to rapidly cool the decorative panel after it has been hot-pressed by the molding assembly, and can simultaneously cool from both the top and bottom sides of the decorative panel. This dual-sided cooling method can effectively improve the cooling speed.

[0008] Preferably, the cooling assembly mainly consists of an upper cold box, a lower cold box, a cold air plate, and refrigeration equipment. The cold air plate is respectively disposed inside the upper and lower cold boxes. The cold air generated by the refrigeration equipment can be transported to the cold air plate and blown directly onto the decorative panel passing along the conveyor track through pre-set air vents on the cold air plate. The upper and lower cold boxes cool the decorative panel from the upper and lower sides respectively. The arrangement of the cold air plate allows the cold air to act more evenly on the surface of the decorative panel, improving the cooling effect.

[0009] Preferably, the cold air plate is supported by the upper and lower cold boxes and is rotatably installed therein, and is connected to a motor. The motor can precisely control the air outlet angle of the cold air plate. This allows for flexible adjustment of the air outlet angle according to the different thicknesses and materials of the decorative panels and the actual cooling needs, further optimizing the cooling effect and ensuring that decorative panels of different specifications can receive uniform and appropriate cooling.

[0010] Preferably, the air outlet of the upper cold box and the air inlet of the lower cold box are connected by a heat-insulated pipe. A fan is also installed inside the heat-insulated pipe. The operation of the fan can accelerate the air circulation in the heat-insulated pipe. Through this structural design, the air circulation between the upper and lower cold boxes is realized, the energy utilization efficiency is improved, and it also helps to maintain the temperature balance inside the entire cooling component.

[0011] Preferably, the exhaust port of the lower cooling box is connected to the air inlet of the refrigeration equipment: this allows the air cooled by the lower cooling box on the decorative panel to return to the refrigeration equipment for refrigeration cycle, further improving energy utilization and reducing energy consumption;

[0012] The air supply duct of the refrigeration equipment is connected to the cold air plate inside the upper cooling box: to ensure that the cold air generated by the refrigeration equipment can be smoothly delivered to the cold air plate of the upper cooling box, and then blown onto the decorative panel;

[0013] A dehumidifier is also installed on the air supply duct: the dehumidifier can dehumidify the cold air delivered by the refrigeration equipment, effectively preventing condensation from forming when the humid air comes into contact with the hot decorative panel due to a sudden drop in temperature, and greatly improving the surface quality of the decorative panel.

[0014] Beneficial effects:

[0015] 1. The cooling components adopt a double-sided cooling method, which greatly improves the cooling speed and ensures the uniformity of cooling, reduces the deformation of the decorative panels caused by uneven cooling, and improves the product qualification rate.

[0016] 2. The cooling plate is rotatable and the air outlet angle can be precisely controlled. It can be flexibly adjusted according to the characteristics of different decorative panels to further optimize the cooling effect and meet diverse production needs.

[0017] 3. The upper and lower cold boxes are connected by insulated pipes and equipped with fans to achieve air circulation and improve energy efficiency;

[0018] 3. The dehumidifier prevents condensation from damaging the surface quality of the decorative panels, further improving product quality;

[0019] 4. In addition, the components work closely together, and the conveyor track ensures stable delivery of the decorative panels. The entire device has good structural coordination, which effectively improves production efficiency and product quality stability. Attached Figure Description

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] like Figure 1 The PVC decorative panel 15 molding device shown includes a molding body 1, a molding assembly 2, and a cooling assembly, specifically:

[0024] The molding body 1 and the conveying track: The molding body 1 serves as the supporting structure of the entire device. The conveying track on it adopts a high-precision linear slide rail to ensure the stability and straightness of the decorative panel 15 during the conveying process. The surface of the conveying track is specially treated to have low friction, which allows the decorative panel 15 to move smoothly. The speed of the conveying track can be precisely controlled by a motor and a frequency converter to adapt to the requirements of different production processes on the conveying speed of the decorative panel 15. For example, for thinner decorative panels 15, the conveying speed can be appropriately reduced to ensure sufficient time for quality during molding and cooling; while for thicker decorative panels 15 with faster heat dissipation, the conveying speed can be appropriately increased to improve production efficiency.

[0025] Compression molding assembly 2: Compression molding assembly 2 includes a heating plate and a pressure application device. The heating plate adopts ceramic heating technology, which can quickly heat up and achieve precise temperature control. During the hot pressing process, the temperature of the heating plate can be precisely controlled within a suitable range according to the material characteristics of the decorative panel 15 and the PVC film.

[0026] Currently, the molding component 2 is a mature component in this field, so we will not go into too much detail here.

[0027] Cooling components:

[0028] The system includes an upper cooling box 3, a lower cooling box 5, and a cooling air plate 4. Both the upper and lower cooling boxes 3 and 5 are made of high-quality heat insulation materials to reduce heat loss. The cooling air plate 4 is made of aluminum alloy, which has good thermal conductivity and can quickly transfer cold air to the surface of the decorative panel 15. Multiple air vents are evenly distributed on the cooling air plate 4. The shape and size of the air vents ensure that the blown cold air can evenly cover the surface of the decorative panel 15. The connection between the motor and the cooling air plate 4 adopts a high-precision rotating shaft and transmission mechanism to ensure that the motor can accurately control the rotation angle of the cooling air plate 4. In actual production, for a decorative panel 15 with a thickness of 5mm, the air outlet angle of the cooling air plate 4 can be adjusted to 30° with the surface of the decorative panel 15, so that the cold air can better contact the decorative panel 15 and improve the cooling effect.

[0029] Insulated duct 6 and fan 14: The insulated duct 6 is made of high-temperature resistant and heat-insulating material. It connects the air outlet 7 of the upper cold box and the air inlet 8 of the lower cold box. For example, it is a polyurethane foam sandwich tube, which effectively reduces the heat transfer in the duct. The fan 14 is a high-performance axial flow fan. Its speed can be adjusted by frequency converter. When the device is running, the fan 14 starts to accelerate the air circulation in the insulated duct 6, so that the air discharged from the upper cold box 3 can quickly enter the lower cold box 5 to realize the recycling of air.

[0030] Refrigeration equipment 11 and dehumidifier 13: The exhaust port 9 of the lower cold box 5 is connected to the air inlet of the refrigeration equipment 11 through the air inlet duct 10. The refrigeration equipment 11 adopts a compression refrigeration system, which has high-efficiency refrigeration capacity and can quickly cool the air to the required temperature, such as cooling the air to 10-15℃, to meet the need for rapid cooling of the decorative panel 15. The dehumidifier 13 installed on the air supply duct 12 is a rotary dehumidifier, which has the characteristics of high dehumidification efficiency and stable performance. Before the cold air enters the cold air plate 4 of the upper cold box 3, the dehumidifier 13 dehumidifies it, reducing the air humidity to a suitable range, such as controlling the relative humidity at 30%-40%, effectively avoiding the generation of condensation and ensuring the surface quality of the decorative panel 15. In the actual production process, when the ambient humidity is high, the dehumidifier 13 can work stably, ensuring that the produced decorative panel 15 still has good quality even under humid weather conditions.

[0031] Through the coordinated operation of the above components, this PVC decorative panel 15 molding device can effectively solve the problems in the existing technology, stably produce high-quality PVC decorative panels 15, improve production efficiency, and meet the market demand for high-quality PVC decorative panels 15.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
